Product Description
The SCG002 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the SCG002 typically provides 21
dB of gain, +29 dBm Output IP3, and +15.5 dBm P1dB.
The SCG002 consists of Darlington pair amplifiers using
the high reliability InGaP/GaAs HBT process technology
and only requires DC-blocking capacitors, a bias resistor,
and an inductive RF choke for operation. The device is
ideal for wireless applications and is housed in a lead-
free/green/RoHS-compliant SOT-89 SMT package. All
devices are 100% RF and DC tested.
The broadband MMIC amplifier can be directly applied to
various current and next generation wireless technologies
such as GPRS, GSM, CDMA, and W-CDMA. In addition,
the SCG002 will work for other various applications within
the DC to 6 GHz frequency range such as CATV and
mobile wireless.
